It strikes me as being fairly simple:
I'd provide the auction winner and DeaDTerra with a fresh BTC address, and explain to DT that (upon funding of that address with the agreed-upon amount) I transfer my claim on 1 of his 5 Jupiters from his top-500 queue order to the auction winner. (He's already posted as to his confirmation and cooperation with this sale)
DT will coordinate with the winner for either physical delivery, or hosting by KNC:
For physical delivery, DT would either provide KNC with the shipping address for the single unit, or pick it up himself and ship it to you (winner pays freight) For KNC hosting, I suppose KNC would provide you with access to the unit, or you'd provide KNC with pool information for that one unit.
